I’m trying to get this hub to work with my laptop. I have 3 Vizio tv’s that I have been using for monitors with my desktop, but it will not work with my laptop. I can connect 1 tv via HDMI straight to the laptop and it will recognize it. The laptop recognizes(chimes) that the hub is connected, but it only displays it as a USB 2.0 BILLBOARD. I have checked for updated drivers, windows updates, etc. I also ran your debug tool, but I am unsure what to do with that output.
Device Info
Processor AMD Ryzen 9 6900HX with Radeon Graphics (3.30 GHz)
Installed RAM 32.0 GB (27.7 GB usable)
System type 64-bit operating system, x64-based processor
Pen and touch No pen or touch input is available for this display
Hello and thanks for posting and the description of what you are seeing! We’ll be happy to help.
Can you tell us the specific model of your laptop? The USBC-MSTH3 requires that the laptop supports video output from the USB-C port, also known as USB-C DisplayPort Alternate mode.
My name is Michael S. and I would be happy to help assist with your issue.
Given your description of the issue, as Wash mentioned the USBC-MSTH3 is dependent on your host providing a USB-C port that is DP Alt Mode capable. I would be happy to take a closer look at your setup to see if we can determine if this is a compatibility issue, or something else.

Thank you for the responses. The laptop in question is a WVX off Amazon. I did end up solving this with a somewhat random solution I found online. I believe it was posted in a Lenovo group, but it worked for me.
Close all programs, unplug everything from the laptop and shut it down.
Press and hold power button for 40 seconds (computer should momentarily boot then shut back down but keep holding until 40 second mark).
Boot laptop up like normal and plug power and hub back in.
I’d say within 30 seconds or so of plugging everything back in, the screens were recognized. I’m now running my 3 screens with no problems.
That’s fantastic news, and thank you so much for sharing the solution you found.
That 40-second power-hold reset you mentioned is a great trick. It forces the laptop’s embedded controller and USB subsystem to reinitialize completely, which can often clear out any odd state or firmware hang-ups that prevent hubs or MST adapters from being recognized properly. We’ve seen this help with a few models, so your post will definitely be useful to others who might run into a similar issue.
We’re thrilled to hear that everything is now working and that you have all three screens up and running smoothly! Thanks again for taking the time to update the thread with your findings.
